I think you mean the 335i (the 330i has a single outlet like yours). Do a search mate, it's been covered quite a few times...

330's have a single box with twin pipes:

335's have two boxes with single pipes:

If its a 320d you have, the 330d system will fit right on if you get the whole system.

The petrol models are a bit different as the front part of the 6 cyl exhaust has two pipes, however the rear box can probably be fitted with a sleeve clamp or reducer.

If you want a dual box system like the 335's use, then you'll need a new boot floor amongst other things.
